Betrayal trauma after infidelity is a useful psychological framework for understanding why the discovery of an affair can destabilize trust, safety, identity, attention, sleep, and emotional regulation. The term describes a way of conceptualizing the impact of betrayal by a trusted or depended-upon person. It is not a psychiatric diagnosis, and intense distress after infidelity does not by itself establish post-traumatic stress disorder (PTSD).

The strongest evidence supports a precise middle position. Infidelity can be followed by clinically important post-traumatic stress symptoms, depression, anxiety, intrusive thinking, hypervigilance, grief, and impaired functioning in some people. At the same time, the research base remains limited, samples are often narrow, and the formal diagnostic rules for PTSD are more specific than the everyday use of the word trauma. A 2025 systematic review of non-Criterion A intimate-relationship stressors found that infidelity and other relationship stressors can be associated with clinically significant post-traumatic stress symptoms, while also finding substantial variability and a sparse literature.

This distinction matters because people often need two things at once after discovering infidelity: language that accurately recognizes the magnitude of what happened and clinical language that does not turn a painful relationship event into a diagnosis that has not been established. This article explains what betrayal trauma means in the context of infidelity, which reactions research has documented, how those reactions differ from PTSD, what the evidence can and cannot show, and when professional support may be useful.

What Does “Betrayal Trauma” Mean After Infidelity?

Betrayal trauma theory was developed by psychologist Jennifer J. Freyd to explain how the relational context of harmful events can shape psychological responses. The theory emphasizes the significance of harm committed by someone on whom a person depends or whom they need to trust. In its original development, the framework focused especially on abuse and dependency rather than romantic infidelity. Freyd, DePrince, and Gleaves describe betrayal trauma theory as an approach that places social relationships and dependence at the center of post-traumatic outcomes.

That history is important. The contemporary phrase “betrayal trauma after infidelity” extends a broader betrayal framework into the context of romantic betrayal. It can be psychologically useful when the central injury is not merely that a partner had contact with someone else, but that a trusted relationship, a shared account of reality, and expectations of honesty or exclusivity were disrupted at the same time.

A separate psychological analysis by Stanley Rachman identified infidelity and dishonesty among common forms of betrayal and described possible consequences including shock, grief, preoccupation, damaged self-esteem, self-doubt, and anger. Rachman’s 2010 analysis of betrayal was conceptual rather than a population estimate, but it helps explain why betrayal can become psychologically significant without implying that every betrayal produces a disorder.

Betrayal trauma is a framework, not a diagnosis

“Betrayal trauma” is not a stand-alone diagnosis in the DSM or ICD. It is a theoretical and research framework used to organize how betrayal, dependence, trust, and psychological harm may interact. The World Health Organization’s ICD-11 clinical diagnostic manual provides formal requirements for recognized mental, behavioral, and neurodevelopmental disorders; betrayal trauma is not a separate disorder within that diagnostic system.

A framework and a diagnosis answer different questions. A framework can help explain why an experience is destabilizing. A diagnosis requires a defined pattern of symptoms, duration, impairment, exclusions, and, for some disorders, a qualifying type of exposure. Someone can experience severe betrayal-related distress without meeting criteria for PTSD, major depressive disorder, an anxiety disorder, obsessive-compulsive disorder, or another psychiatric condition.

Infidelity is not a mental disorder

Infidelity is a relationship behavior or boundary violation, not a mental disorder. It can occur in many interpersonal contexts and for many different reasons. The fact that one partner cheated does not diagnose that person with a personality disorder, compulsive sexual behavior disorder, an attachment disorder, or any other condition. Likewise, the betrayed partner’s reaction should not be converted automatically into a psychiatric label.

For a broader research-based definition of the behavior itself, see What Is Infidelity? Meaning, Types, Examples, and What Research Shows. The present article owns the narrower question of betrayal-trauma language and the psychological aftermath of infidelity.

Why Can Infidelity Feel Traumatic?

Infidelity can create several disruptions at once. The event may alter what a person believes about the relationship, what they believe happened in the recent past, what they expect from the future, and how confidently they trust their own interpretations. Discovery can therefore function as both a painful event and a sudden revision of personal history: ordinary memories, trips, messages, absences, sexual experiences, conflicts, and reassurances can acquire new meanings after new information appears.

This is one reason betrayal-related distress often involves more than sadness. The betrayed partner may be trying to understand an event while also reassessing the reliability of the person who would ordinarily be a source of comfort. When the same relationship is simultaneously associated with attachment, practical interdependence, emotional safety, uncertainty, and injury, approach and avoidance can coexist: a person may want reassurance and distance, answers and relief from details, closeness and protection.

Betrayal trauma theory gives this conflict a relational interpretation. In broader betrayal-trauma research, higher-betrayal experiences have been associated with psychological distress and some health outcomes, although those studies are not infidelity-specific. For example, a community study by Freyd, Klest, and Allard linked histories of high-betrayal trauma with anxiety, dissociation, depression symptoms, and physical illness in adults with chronic medical illness or pain. It supports the broader framework while not establishing that infidelity produces the same effects or mechanisms.

Common Reactions After Infidelity

There is no single betrayal-trauma symptom profile that every betrayed partner experiences. Reactions vary in intensity, duration, combinations, and functional impact. The same person may move between states rather than remain in one emotional pattern. The following reactions are reported in research and clinical literature, but none of them alone establishes a diagnosis.

Intrusive thoughts and mental replay

People may repeatedly replay the moment of discovery, imagine scenes they did not witness, revisit messages, reconstruct timelines, or find unwanted questions returning during work, sleep, sex, or ordinary routines. These thoughts can feel involuntary and exhausting. In a small study of unmarried young adults who had experienced a partner’s infidelity, Roos and colleagues documented substantial post-traumatic stress symptom levels, including symptom patterns involving intrusion.

Intrusive thoughts after infidelity are not automatically obsessive-compulsive disorder. OCD involves a broader diagnostic pattern of obsessions and/or compulsions, with specific clinical requirements and functional consequences. Repeated thinking after a major relationship shock may instead reflect acute distress, rumination, uncertainty, attempts to make sense of conflicting information, or trauma-like intrusions. The content of a thought is not enough to determine its diagnosis.

Hypervigilance and threat monitoring

A betrayed partner may become unusually alert to cues that now seem connected to deception: changes in routine, unexplained absences, a phone notification, a location, a name, a time of day, a social-media interaction, or a gap in a story. This scanning can temporarily feel protective because the discovery showed that important information could be hidden.

Hypervigilance can become distressing when the nervous system remains persistently activated or when monitoring expands across daily life. Still, hypervigilance is a symptom description, not proof of PTSD. It also does not establish that a new act of infidelity is occurring. Behavioral changes and ambiguous cues can raise questions, but they are not evidence by themselves; that distinction is developed separately in Signs of Infidelity: What May Raise Questions—and What Does Not Prove Cheating.

Sleep disruption and physiological arousal

After discovery, some people report trouble falling asleep, waking early, nightmares, appetite changes, agitation, muscle tension, difficulty relaxing, or a sense of being constantly on guard. These reactions can occur in many forms of acute stress and emotional upheaval. Their clinical meaning depends on severity, persistence, associated symptoms, medical factors, and the degree to which daily functioning is affected.

Emotional volatility, numbness, and grief

Anger, sadness, fear, humiliation, longing, disbelief, relief, shame, disgust, tenderness, emotional numbness, and grief can appear in rapid succession. Contradictory emotions do not mean the person is confused in a pathological sense. Betrayal can create multiple losses at once: the loss of an assumed relationship narrative, certainty about the past, anticipated future plans, or a particular image of the partner.

Self-doubt, comparison, and changes in self-concept

Infidelity can prompt questions such as “How did I miss this?”, “Was any of it real?”, “What does this say about me?”, or “Why was the other person chosen?” These interpretations can affect self-esteem and identity even when the decision to be unfaithful was made by the other partner. Shrout and Weigel’s study of 232 college students found that appraisals such as self-blame and partner blame were linked indirectly to health-compromising behaviors through depression, anxiety, and distress. The sample and design limit broad causal conclusions.

Avoidance and trigger sensitivity

Some people avoid locations, songs, dates, conversations, sexual situations, social events, or digital platforms associated with the affair. Others feel strong reactions when reminders appear unexpectedly. Trigger sensitivity can be understood as learned meaning: a previously neutral cue becomes connected with discovery, deception, or painful information. A trigger can therefore produce a strong reaction without proving that danger is currently present.

Depressed mood, anxiety, and impaired functioning

Infidelity can be associated with depressive and anxiety symptoms, but symptom presence is different from a diagnosed disorder. In a probability-based study of 227 married or cohabiting adults selected because they were at elevated risk for depression due to low relationship satisfaction, Whisman found that discovering a partner affair was associated with a higher prevalence of past-year major depressive episode and lower marital adjustment. Because the sample was deliberately high-risk, those results should not be treated as prevalence estimates for all betrayed partners.

In the Roos et al. study, infidelity-related post-traumatic stress symptoms were also associated with depressive symptoms, while findings for anxiety and perceived stress were mixed. These studies support careful mental-health assessment when distress is severe; they do not show that infidelity inevitably causes depression, anxiety, or PTSD.

What Does the Evidence Actually Show?

The evidence base is meaningful but smaller than the popularity of the term “betrayal trauma” online might suggest. Research includes theoretical work on betrayal, small infidelity-specific studies, relationship-stress studies, clinical literature, and a growing review literature. The strongest conclusion is that infidelity can be followed by clinically important trauma-like and mood symptoms in some people, while the frequency, severity, mechanisms, and diagnostic implications remain insufficiently established for universal claims.

Roos et al. (2019): an important signal from a narrow sample

One of the most frequently cited infidelity-specific studies included 73 unmarried adults with a mean age of about 19 who had experienced infidelity in a committed relationship within the previous five years. Roos et al. reported that 45.2% had symptom scores suggesting probable infidelity-related PTSD in that study and that higher symptom levels were associated with poorer psychological health.

That 45.2% figure should not be read as “45% of people who are cheated on develop PTSD.” The study was small, young, unmarried, and based on symptom measures rather than a representative clinical diagnostic survey of all betrayed partners. The authors framed the result as probable infidelity-related PTSD symptoms. A screening or symptom threshold is not equivalent to a confirmed diagnosis, and a DSM PTSD diagnosis also requires a qualifying Criterion A exposure.

Earle et al. (2025): the systematic review finds a real but limited literature

A 2025 systematic review by Earle and colleagues examined post-traumatic stress symptoms after intimate-relationship stressors that do not necessarily meet DSM-5-TR Criterion A. Only nine studies met the review’s inclusion criteria, and only two focused on infidelity. The review concluded that infidelity, relationship conflict or divorce, and psychological abuse can be associated with clinically significant post-traumatic stress symptoms, but findings were not consistent across studies and the literature remains sparse.

This review is especially useful because it preserves the distinction between symptoms and diagnosis. It shows that a person can experience a post-traumatic symptom pattern after a non-Criterion A relationship stressor without making the diagnostic rules of PTSD disappear.

Depression and distress evidence supports assessment, not inevitability

Whisman’s study supports an association between recent affair discovery and major depressive episode in a selected high-risk sample, while Shrout and Weigel’s work links appraisals after infidelity with depression, anxiety, distress, and health-compromising behaviors in college students. Together, these studies make a strong case for taking post-infidelity mental health seriously. They do not establish one deterministic pathway from betrayal to disorder.

Betrayal theory contributes a mechanism, not an infidelity diagnosis

Freyd’s betrayal trauma theory contributes a hypothesis about why harm within a needed or trusted relationship may be psychologically distinctive. That is different from saying the theory was developed as a diagnostic model for affairs. The theory’s foundational literature is broader and historically centered on abuse, dependency, memory, and relational survival. Applying it to infidelity should therefore be done explicitly as a framework rather than presented as if “betrayal trauma from cheating” were a formal clinical category.

Betrayal Trauma vs. PTSD After Infidelity

Betrayal trauma and PTSD are not interchangeable terms. Betrayal trauma is a conceptual framework. PTSD is a formal diagnosis with specific exposure and symptom requirements.

The U.S. Department of Veterans Affairs National Center for PTSD summarizes DSM-5-TR Criterion A as exposure to death, threatened death, actual or threatened serious injury, or actual or threatened sexual violence through defined routes of exposure. The DSM-5-TR PTSD summary also requires a specific pattern of intrusion, avoidance, negative changes in thoughts or mood, arousal/reactivity, duration, distress or impairment, and exclusion criteria.

Infidelity by itself generally does not match that Criterion A definition. A person can therefore experience intense post-traumatic stress symptoms after infidelity while the affair itself does not qualify as the Criterion A event required for a DSM-5-TR PTSD diagnosis. If the surrounding circumstances include sexual violence, physical violence, credible threats of serious injury or death, or another qualifying exposure, clinical assessment may reach a different conclusion based on that qualifying event.

Trauma-like symptoms do not automatically mean PTSD

Intrusive memories, nightmares, hypervigilance, avoidance, sleep problems, negative beliefs, irritability, emotional numbing, and concentration problems can resemble PTSD symptom clusters. They can also occur in other stress responses and psychiatric conditions, or during severe but non-disordered distress. Diagnosis depends on the complete clinical picture, not on symptom resemblance.

A screening score is not a diagnosis

This point is particularly important when reading online claims based on questionnaires. The VA’s guidance on the PTSD Checklist for DSM-5 (PCL-5) states that the instrument can screen for PTSD and support a provisional diagnosis, while a structured clinical interview such as the CAPS-5 is the diagnostic gold standard. The VA also notes that interpretation should account for population and purpose. A high score after infidelity indicates significant symptoms worthy of attention; it does not, by itself, establish a formal PTSD diagnosis.

“Post-infidelity stress disorder” is not an official diagnosis

The phrase “post-infidelity stress disorder” or PISD appears in popular and clinical-adjacent discussions, but it is not an official diagnosis in DSM-5-TR or ICD-11. It may function informally as shorthand for severe distress after infidelity. It should not be presented as if it were a recognized psychiatric disorder with validated diagnostic criteria.

Betrayal Trauma, Intrusive Thoughts, and OCD Are Different Questions

One of the most common post-infidelity experiences is repetitive unwanted thinking. A betrayed partner may replay conversations, search memory for missed clues, compare timelines, imagine sexual or emotional details, or feel compelled to revisit the discovery. That experience can be intensely distressing without being OCD.

OCD is diagnosed from a characteristic pattern involving obsessions and/or compulsions, along with distress, time burden, impairment, and other clinical requirements. Repetition alone is not enough. An intrusive thought can occur in grief, acute stress, depression, anxiety, trauma-related conditions, relationship uncertainty, and ordinary emotional processing. Labeling every unwanted thought “OCD” collapses clinically different phenomena into one term and can lead to the wrong self-treatment.

Rachman’s betrayal analysis discussed links between catastrophic betrayal, mental contamination, and obsessive-compulsive phenomena in some clinical contexts. That work shows why betrayal can be relevant to OCD assessment in selected cases; it does not mean that intrusive thoughts after an affair are presumptively OCD.

What Can Make Post-Infidelity Distress More Intense?

Research does not support a simple formula in which one feature determines the outcome. Distress is shaped by interacting characteristics of the betrayal, the relationship, the discovery, the person, and the environment. These should be treated as possible contributors or correlates, not deterministic causes.

Repeated deception and continuing uncertainty

Distress may be harder to settle when major information continues to change, new disclosures repeatedly alter the timeline, or the outside relationship is still active. The psychological task is different when the event is clearly in the past than when the betrayed partner is still trying to determine whether deception is ongoing.

The manner of discovery

Unexpected discovery can add shock and loss of orientation. Learning through a message, another person, a health concern, a public exposure, or contradictory evidence can shape the meaning of the event. How someone learns about an affair can therefore influence the immediate crisis even though no single discovery method predicts a specific diagnosis.

Dependence and practical entanglement

Shared housing, finances, children, caregiving, immigration status, social networks, work, or other forms of interdependence can make relational decisions more consequential. Betrayal trauma theory is especially attentive to situations in which the person associated with harm is also connected with needed security or support.

Prior vulnerabilities and current resources

Previous trauma, existing depression or anxiety, sleep problems, current life stress, social isolation, financial pressure, and limited support may affect how a person responds. Protective resources such as stable housing, supportive relationships, competent professional care, and the ability to make decisions without coercion may also shape recovery. These factors influence risk and resilience; none creates a predetermined outcome.

When Infidelity Occurs Alongside Coercion, Gaslighting, Stalking, or Violence

Infidelity alone does not establish psychological abuse, coercive control, gaslighting, narcissism, or any personality disorder. Those are separate questions that require evidence about specific patterns of behavior.

A 2026 narrative review by Rebecca Ward examined serial infidelity specifically when it occurred with sustained deception, coercive control, gaslighting, or psychological abuse. The review synthesized 47 peer-reviewed studies and argued that repeated betrayal embedded in coercive patterns can have trauma-related consequences. Its scope is important: it does not justify relabeling every affair as abuse.

When threats, stalking, intimidation, sexual coercion, physical violence, financial control, or other abuse is present, safety takes priority over relationship-preservation goals. The immediate question becomes how to reduce danger and increase independent support, not how quickly the couple should reconcile. Couples work can be inappropriate or unsafe in some coercive situations because joint disclosure and confrontation may increase risk.

What Recovery From Betrayal-Related Distress Can Look Like

Recovery does not require one prescribed sequence. Some people remain in the relationship, some separate, some delay the decision, and some move between possibilities while the crisis becomes clearer. Healing can occur with or without reconciliation and with or without forgiveness. A person’s mental-health recovery and the future of the relationship are related questions, but they are not the same question.

Stabilizing basic functioning

Early recovery may involve restoring sleep, nutrition, daily routines, work capacity, childcare, social contact, and enough emotional regulation to make decisions. This is not a formula for “moving on.” It is a way of reducing the degree to which the crisis controls every hour of the day.

Developing a coherent account of what happened

Uncertainty can keep attention locked on unresolved questions. People often need enough reliable information to understand what happened and what the current situation is. More detail is not always better: exhaustive sexual or sensory detail can intensify imagery for some people. The useful level of disclosure depends on the purpose of the information, the person’s needs, clinical context, and safety.

Reducing self-blame without erasing complexity

A relationship may have had serious problems before an affair, and those problems can deserve examination. That does not make the betrayed partner the agent of another person’s decision to violate an agreement. Separating relationship context from responsibility for the infidelity can help prevent global self-condemnation while still allowing a realistic review of the relationship.

Rebuilding trust in one’s own perception

Betrayal can make people doubt their judgment, especially when earlier concerns were repeatedly dismissed or contradicted. Recovery may therefore include rebuilding confidence in one’s ability to notice uncertainty, ask questions, tolerate incomplete information, set boundaries, and make decisions without requiring impossible certainty.

Professional support when symptoms are persistent or impairing

Current American Psychological Association coverage of infidelity treatment describes several evidence-informed approaches used by psychologists and emphasizes that therapy may support repair, individual recovery, discernment, or separation. Treatment should fit the actual presentation: infidelity itself is not a disorder to be treated, and not every betrayed person needs trauma-focused therapy.

A clinician may assess mood symptoms, anxiety, sleep, substance use, trauma history, current safety, relationship context, and the presence of qualifying traumatic exposures before deciding what formulation and treatment approach fit. When a formal disorder is present, evidence-based treatment should target that disorder rather than an internet label.

There Is No Evidence-Based Universal Timeline for Betrayal Trauma

Search results often offer fixed recovery schedules such as six months, one year, two years, or several years. The scientific literature does not establish a universal timetable that can predict when a particular person will feel recovered after infidelity. Recovery time depends on what happened, whether betrayal or deception is continuing, mental-health symptoms, practical circumstances, safety, social support, relationship decisions, and many other factors.

Progress can also be nonlinear. A reminder, anniversary, new disclosure, sexual difficulty, legal step, or unexpected encounter may temporarily intensify distress. A setback does not prove that recovery has failed or that the person has “returned to day one.” Conversely, feeling calmer for a period does not obligate someone to reconcile or to declare the issue resolved.

When to Seek Professional Help

Professional support becomes especially important when distress is severe, persistent, worsening, or interfering with the ability to sleep, work, study, parent, eat, maintain basic routines, or stay safe. Assessment may also be useful when symptoms suggest major depression, severe anxiety, a trauma-related disorder, substance misuse, or another condition that requires more than relationship advice.

Seek urgent local crisis or emergency support if there is immediate risk of suicide, self-harm, violence, sexual coercion, stalking, or threats of serious harm. In these situations, safety planning and individual protection take priority over reconciliation conversations.

If the central problem is uncertainty about whether a partner cheated, therapy should not turn ambiguous signs into proof. If the central problem is repetitive intrusive thinking, clinicians should assess what kind of process is occurring rather than assuming OCD. If the central problem is post-traumatic symptoms, clinicians should distinguish symptom severity from the diagnostic exposure criteria for PTSD. Precision improves care because different problems call for different interventions.

What Betrayal Trauma After Infidelity Does—and Does Not—Mean

It can mean that infidelity has produced a severe relational stress response involving trust, safety, identity, intrusive thinking, vigilance, grief, or emotional dysregulation. It does not mean that “betrayal trauma” is an official DSM or ICD diagnosis.

It can coexist with clinically significant depression, anxiety, or post-traumatic stress symptoms. It does not mean those disorders are present without appropriate assessment.

It can help explain why harm from a trusted or depended-upon partner can feel uniquely destabilizing. It does not prove that every instance of infidelity is abuse, coercive control, gaslighting, or a Criterion A trauma.

It can describe real suffering even when the person does not meet criteria for PTSD. It does not establish a fixed recovery timeline or require reconciliation, forgiveness, or relationship continuation.

Frequently Asked Questions

Is betrayal trauma after infidelity real?

Yes, as a psychological framework and description of betrayal-related distress. Research documents substantial distress and post-traumatic stress symptoms after infidelity in some samples, and betrayal trauma theory provides a relational framework for understanding harm involving trust and dependence. The term itself is not a formal psychiatric diagnosis.

Can being cheated on cause PTSD?

Infidelity can be followed by PTSD-like or post-traumatic stress symptoms. A DSM-5-TR PTSD diagnosis, however, requires a qualifying Criterion A exposure in addition to the required symptom pattern, duration, impairment, and exclusions. Infidelity by itself generally does not meet Criterion A. If the circumstances also involve violence, sexual violence, serious injury, or credible threats that qualify, a clinician would assess those exposures separately.

What are common betrayal-trauma symptoms after cheating?

Reported reactions include intrusive thoughts, mental replay, hypervigilance, sleep problems, emotional volatility or numbness, grief, anger, anxiety, depressed mood, self-doubt, concentration difficulty, avoidance, and strong reactions to reminders. These are symptom descriptions, not a checklist that diagnoses a disorder.

Does checking a partner’s phone mean I have trauma or OCD?

No diagnosis can be inferred from one behavior. Checking can arise from uncertainty, fear of renewed deception, attempts to verify facts, compulsive processes, relationship conflict, or other reasons. The function, frequency, controllability, consequences, and wider symptom pattern matter.

How long does betrayal trauma last after infidelity?

There is no scientifically established universal duration. Recovery may be faster or slower depending on the circumstances, whether new betrayals or disclosures continue, symptom severity, safety, support, treatment needs, and relationship decisions. Fixed online timelines should not be treated as prognosis.

Do I have to forgive or stay in the relationship to heal?

No. Psychological recovery, forgiveness, reconciliation, and relationship continuation are distinct outcomes. A person can recover while leaving, while staying, while remaining undecided for a period, or without choosing forgiveness. Safety and autonomous decision-making matter more than following a prescribed relationship outcome.

Can betrayal trauma happen after emotional or online infidelity?

Severe distress can follow different kinds of boundary violations, but emotional, online, sexual or physical, and financial infidelity should not be collapsed into one construct. The psychological impact depends on what occurred, what agreements were violated, the meaning of the behavior within the relationship, and the surrounding deception or consequences. Whether a behavior counts as cheating in the first place is addressed in What Counts as Cheating? Boundaries, Secrecy, Intent, and Relationship Agreements.

The Evidence-Based Bottom Line

Betrayal trauma after infidelity is best understood as a psychological framework for a potentially severe response to relational betrayal. It names an important dimension of the experience: the person associated with trust, intimacy, and security is also connected with the event that disrupted those expectations.

The evidence supports taking these reactions seriously. Infidelity-specific studies and a recent systematic review show that some people experience clinically significant post-traumatic stress symptoms, depression, anxiety, intrusive thinking, and functional disruption. The evidence also requires precision: the literature is limited, many samples are narrow, symptom measures are not equivalent to diagnoses, and PTSD retains specific diagnostic exposure requirements.

The most accurate language preserves both realities. A person can be deeply affected by infidelity without being assigned a disorder. Betrayal-related distress can warrant clinical attention without converting “betrayal trauma” into a DSM or ICD diagnosis. Recovery can be meaningful without a universal timeline, forced forgiveness, or a predetermined decision to stay together.
